(8752) Flammeus is an asteroid of the inner main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The Italian astronomer Vincenzo Zappalà used a hierarchical cluster analysis in a publication from 1995 (et al.) To extrapolate the asteroid's membership of the Nysa family, a group of asteroids named after (44) Nysa . The group is also called the Hertha family, after (135) Hertha .
The rotation period of (8752) Flammeus was published in 2015 by Adam Waszczak, Chan-Kao Chang, Eran Ofek et al. examined. However, the light curve was not sufficient for a determination.
The asteroid was named on February 2, 1999, after the short-eared owl , whose scientific name is Asio flammeus . At the time it was named, the short-eared owl was on the Dutch and European Red Lists of Endangered Birds.
